- PIANO-BENCH.

To all whom it may concern.-

-Be it knownthat I,JAMEs F. KELLY, a

citizen of the United States, residing at San- Francisco, in the countyof San Francisco. and State of California, have invented a new anduseful PianoBench, of which the following is a specification. 1

The present invention appertains generally to furniture, and relatesmore particularly to piano benches, it being the object of the inventionto provide a novel and improved piano bench, the'top or seat of whichcan be adjusted vertically to either a horizontal or inclined position.The object of the invention'is the provision of a piano bench having anadjustably mounted seat or top as above indicated,

whereby the seat may be elevated to lie in a various horizontal planes,to adjust the height of thebench to suit the occupant when playing anordinary piano, the device 1 being so constructed thatthe seat may also1 be inclined whereby the bench is especially useful in connection witha player or mechanical piano, since the inclined seat will enable theoperator to exert greater pressure upon the pedals of the player ormechanical piano. 1

" As a more specific object, the invention, aims to provide anad ustlngmechanlsm for the seat or top of the bench which is of such constructionthat when the mechanism is operated in one direction, the seat while ina horizontal position is elevated or raised parallel with itself, andwhen the mechanism is actuated in the opposite direction, one edge ofthe seat is elevated with respect to the other to give the desiredinclination to the a seat. a 1

40 It is also within'the scope of the invention to provide an adjustablepiano bench of the nature indicated embodying a unique assemblage of thecomponent elements, and embodying improved detailsof construction, to

46 enhance the utility and efliciency of'the-device, the bench beingcomparatively simple and inexpensive in construction, and the parts ofthe adjusting mechanism with the exception of the knob or actuatingmember 50 beingconcealed below theseat.

With the foregoing'and other .objects in view whic'h will appear as'thedescription proceeds, the invention resides in the com bination andarrangement of parts and in the details of construction hereinafter de-,scribed and claimed, it being understood that Specification of LettersPatent.

changes in the precise embodiment'of the invention herein disclosedcan-be made within the scope of what is claimed without de-' partingfrom the spirit of the invention.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is abottom iew of the improved I bench. Fig. 2 is alongitudinal section thereof taken on the line 2-2;ofFig. 1.

,Fig. 3 is an enlarged cross section taken on longitudinal rails 2terminally secured to the legs, and cross or transverse rails 3terminally secured to the legs ,adjacent'the upper ends thereof. Thelegs 1 and rails 23 provide the frame of the bench, above which therectangular seat or top 4 is vdisposed. The said seat is provided with amarginal depending apron or rim '5 overlapping the upper rails 2-3to'give the bench a neat appearance, and to close the gap betweentheframe and seat when the seat is elevated. The frame and seat may beconstructed of wood or other suitable material, and may be finished inany desired manner.

- Vertical posts or standards 6 have their upper ends bifurcated andpivoted, as at 7 I to the depending flanges of T-irons or cle'ats 8secured in any suitable manner to the lower surface ofthe'seat't, theirons8 preferably extending. transversely of the seat above the legs atthe opposite ends of the frame. The posts 6'fit slidably within ver'tical bores 9 provided in the upper terminals of, the legs, and the legsare provided with vertical slots 10 and communicating with The upperends of the slots 10 are open and extend to the upper ends of the legs,and outstanding pins 11 are secured to the posts 6 to project throughand, work within the slots 10. ,A'roller l2'is mounted upon theprojecting portion of each pin 11.

[The frame carries means for adjusting the posts 6 vertically for thepurpose of adjusting the seat'which is carried by said, posts,

- carried by each end of the frame, the levers and to this end, a pairof levers 13jl4 is being fulcrumed or; pivoted between their ends bymeans of screws or pivot elements 15 to the inner sides of the end.rails 3. The

adjacent arms of the levers 13-44 are provided with reduced overlappedportions 16-47, respectively, and the remote arms of the levers projectunder and bear upwardly against the rollers 12, whereby the posts 6 aresupported by the remote arms of the levers. When the seat is in loweredposition, the remote arms of the levers seat upon outstanding pins orstops 18 carried by the legs 1.

In order to swing the levers-for adjusting the posts 6, a longitudinalshaft 19 is journaled through a bushing 20 engaged through one of theend rails 3, and is provided at its respective end with a knob or handle21 upon the outside of the bench frame, where- ,by the shaft may bemanipulated conveniently, the knob 21, however, not being unsightly inappearance or cumbersome. The other end of the shaft 19 is journaled toa plate mounted slidably upon pins23 carried by the other end rail 3within arecess 2% therein, coiled wire expansion springs 25 beingdisposed upon the pins 23 between the plate 22 and the respective rail3, whereby the shaft 19 is yieldably moved toward the opposite end ofthe frame. Eccentrics or cams 26 are secured in any suitable manner uponthe shaft 19 above the overlapped endsof the levers, and bear upon theoverlapped ends of the levers.

A plate 27 is secured to the inner side of that end rail 3 having thebushing 20, and'is provided with an annular series of apertures 28 and apin 29 is carried. by the respective eccentric 26 and is adaptedito beprojected into one of the apertures 28 under the influence of thesprings 25, whereby the shaft 19 is held in the position to which it isturned. The eccentrics 26 are slidable upon the levers without movingoff of the same, so that when the shaft 19 is pressed inward by the knob21, the pin or lug 29 inner arms of the levers 11 will be depressed alsosince the ends 16 of the levers 13 bear upon the ends 17 of the levers 11, and as a result the outer or remote arms of the levers will swungupwardly, as a whole, for raising the posts 6 and seat 4 carriedthereby, the seat remaining in a horizontal pposition. The seat can beelevated to various positions according to the positionto which theeccentrics are rotated, and the seat may be 'heldat' any elevatedposition by properly releasing the shaft 19 so that the pin 29 isprojected into the respective aperture of the plate 27, whereby theshaft 19 is prevented fromrotating. The bench is thus useful for playingan ordinary piano, the seat being adjustable to properly accommodate theperson playingv the piano.

Supposing it is desired to use the bench with a player ormechanicalpiano, in which event it is desirable to have the seat11101111811 so that the operator canexert the required pressure upon thepedals, the shaft 19 after being released, is rotated in the proper direction to swing the eccentric26' onto the inner arms of the levers 14instead of the levers 13, and as a consequence, the inner arms of thelevers 11 will be swung-downwardly withoutappreciably swinging thelevers 13, andthis causes the outer arms of the rear levers 14 to beswung upwardly relative to the. levers 13, whereby the rear posts 6 areelevated to raise the rear portion of the seat. may be brought to thedesired inclination by properly manipulating the shaft 19, the

seat being held in an inclined position when the pin 29 is engaged withthe proper taper ture of the plate 27; ,The inclined position of theseat is illustrated in dotted lines in Fig. 3. The desired verticaladjustment to bring the seat man elevated horizontal po- The seat isthus inclined, and

sition or an inclined positionwis readily accomplished by rotatingtheshaft 19 in one direction or the other, theadvantages of which will bereadily apparent.
